Almost brand new Dell keyboard defect no covered by warranty

After just 3 months, the “L” key popped off my R25,499 Dell Latitude 5450 laptop . Dell SupportAssist’s verdict? “Accidental damage.” There’s no plausible way normal use could cause this - it’s clearly a defect. Yet keyboard keys aren’t covered under warranty. Apparently expecting to type without keys falling off was too much to ask. One star, solely for having a virtual assistant. Really, Dell. Surely you can do better than this? How do you sleep at night knowing you're selling defective keyboards?
